PERMUTAIION-LOUK FOR LATGH-LEVEES.

a citizen of the United States, residing at Admire, in the opunty of Lyon and State of Kansas, have invented certain new and useful Improvements in Permutation-Locks for Latch-Levers, of which the following is a specification.

This invention relates to an improved lock device and while .it is capable of general use, is particularly adapted for use with a brake lever of an automobile and the principal object of the invention is to so con struct this device that it may look the lever or other article in a set position so that unauthorized persons cannot operate and steal the automobile 'or article, it being necessary to set the combination in order to move the osition.

Another object 0 the invention is to so construct this lock that the locking mechanism will be contained in the head or handgrip of the lever, the setting disk being mounted above the head and carried by the latch releasing plunger. I I

' Another object of the invention is to so construct this lever that the latch actuating and locking means will be inclosed therein with the exception of theupper end portion of the releasing plunger or rodand setting disk, the plunger extending above the handgrip of the lever to permit the combination to be easily set and to further permit the plunger to be easily reached. with the thumb in order to move the plunger downwardly after the combination has been set.

Another object of theinvention is to so construct this lever that the releasing plunger may be turned .without the latch being turned but to prevent the plunger from being moved downwardly excepting when the combination is set.

The invention 1s illustrated in the accompanying drawings, wheremw- Figure 1 is a view showing the improved latch lever principally in elevation; the lower portion of the lever being shown in section,

The latchv lever is provided with a tubular body 10 having its lower end portion split longitudinally to provide arms which straddle the rack 11 and are pivotally conmeans of the pivot pin 13. p The latching tooth or pawl 14 is positioned beneath the rack bar 11 and is engaged by a spring 15' .bar is slidably mounted upon the reduced end 17 of the plunger 18 and carries hanger rods 19 which extend downwardly through thetubular body 10 upon opposite sides of the rack bar and engage the latching teeth 14 to cause the latching tooth to be moved nected with the cross bars 12 of the rack by downwardly against the tension of spring 7 a 15 when the plunger 18 is moved downment with the cross bar or'yoke 16.

The head or hand-grip 21-which is hollow 1s posit1oned about the upper end portion ofthe plunger 18 beneath the plunger head 22 -wardly to bring the shoulder 20 into engageand has its threaded lower end portion engaged by the threaded collar 23 thus. ro-

rtatably connecting this hand-hold or head with the tubular body A notch is formed in the threaded lower end portion of this handle 21 to receive the tooth 24 of the sleeve 25 and therefore this sleeve willbe connected with the handle. This sleeve 25 rests upon the upper edge of the tubular body thus preventing itfrom moving into the-.

' body and is engaged by the abutment pin 26 to receivethe rib 29.

. theplunger to engage the upper end of this.

extending through the plunger 18. This provision of the abutment /pin 26 prevents the plunger from moving lfpwardly through the sleeve beyond the position shown 1n 2 and 3 and as this sleeve is provided with a bead 27 at its lower end engaged by the handle or hand-grip 21, it will be readily seen that the plunger cannot move upwardly beyond the desired amount. A groove 28 is formed in this sleeve 25 and extends longitudinally through the same so that the rib 4 29 of the lungertmay move downwardly through. the groove when the plunger is pressed. The setting disk 30 is mounted upon the plunger above the head 21 and held against rotation upon the plunger by means of the pin 31 'fitting into the groove 32 and carries indicating characters as shown in Figs. 1 and 3 which will be positioned with respect to the marks 33 of the head 21, when setting the combination.

Within the head 21 there is provided a setting cup 34 positioned upon the plunger and provided with a neck 35 in which there is provided a longitudinally extending slot This cup is cut out to provide a groove or pocket 36 and is provided with openings 37 and 38 into which will be placed the pins 39 and 40. It is of course understood that as many opemngs may be provided as desired and that the pins will be removed from the openings in which they are shown and placed in dlflerent openings when changing the combination. The upper end portion of the sleeve 25 is reduced to provide the neck 41 havin a thickened lower end portion 42. A locking disk 43 is placed about the reduced neck 41 and a larger locking disk 44 is rotatably mounted about the thickened lower portion 42 of this neck, the disk or washer being provided with slots to permit passage of the rib 29 when set in the proper position and being provided with pins 45 and 46 for engagement by the ins 39 and 40 in setting the combination." fter the sleeve 25 is put in place, the disks 43 and 44 are placed upon the upper end of the sleeve and the turning cup is then put in place after which the spring 47 is put in place as shown in Figs. 2 and 3 and the pins 48 passed through spring 47. This spring not only serves to holdthe cup in engagement with the upper end of the sleeve 25 but also serves to normally hold the plunger in the raised position shown, the pins 26 and 49 preventing the plunger from moving upwardly beyond the desired amount. By removing the pin 48, the spring 47 will engage the upper end of the hand-grip 21 thus holding the cup in the position shown in Fig. 3 but permitting the plunger to drop with the rib 29 passing into the groove 28. The head or hand grip 21 is then put in place and engaged by the collar 23 and the setting disk 30 is then sepivotally connected with the cross bar '12 and the lever mounted as shown. When it is desired to start the automobile it is simply necessary to turn the plunger through the medium of the head 22. until the'proper combination has been set through the medium of the disk 30 and the plunger can then be. pushed downwardly thus moving the latch 14 to a releasing position and permitting the lever to be swung upon its pivot pin thus releasing the emergency of the automobile. If thepin 48 has been re moved, it will of course be necessary to raise the plunger to bring the rib 29 above the sleeve 25 before the plunger can be turned. After the lever has been moved to the desired position, the plunger can be released and the springs 47 and 15 will return the mechanism to the normal position, the locking disk of course remaining in the set position for permitting downward movement of the plunger when desired. Upon leaving the machine, the lever can be moved to set the brake and the plunger can then be turned through the medium of the head 22 thus scattering the combination. It would then be impossible to move the lever without the knowledge of the combination. When again entering the machine, the plunger will be moved and turned first in one direction to set one of the locking disks and then in the opposite direction to set the second disk and then given another turn to bring the tongue 29 into the proper position for passing through the alined openings in the locking disks and through the groove 28 in the sleeve 25. Of course, it is obvious that this is only one combination which could be used and that each change of combination would require a difi'erent series of turns to properly set the combination. The lever is therefore so constructed that onlya person knowing the combination can move the same after it has been moved to a setposition and the: combination scattered. There has further been proposed of a comparatively few number of parts soconstructed thatthey will not be liable to easily get out of order.
